Ask Your CPA
Your existing certified public accountant represents one of the most valuable resources for cost segregation provider recommendations. CPAs who work regularly with real estate investors often have established relationships with reputable providers.
Why your CPA is an ideal resource:
Understanding of your specific tax situation and goals
Knowledge of your property portfolio and investment strategy
Established professional network of trusted service providers
Ability to coordinate the cost segregation study with your overall tax planning
Questions to ask your CPA:
Which cost segregation providers have you worked with successfully?
What should I expect in terms of study timeline and deliverables?
How will the cost segregation study integrate with my existing tax strategy?
Can you review the provider's work before filing?
Even if your CPA doesn't regularly handle cost segregation studies, they likely have professional connections who can provide qualified referrals.
How to use it smartly:
Schedule a meeting to discuss cost segregation strategy before seeking referrals
Ask your CPA to participate in initial provider interviews to ensure alignment
Request that your CPA review the provider's methodology and sample reports
Ask for referrals to multiple providers to ensure competitive options
Vetting Criteria (Don’t Skip These)
No matter how good your source is, every provider you consider should pass these minimum checks:
Criterion | Why It Matters | Quick Test |
|---|---|---|
Certification | Shows they are committed to best practices | Ask for certificates and if the engineers are US based |
In-house engineering / technical capacity | Cost segregation is an engineering + tax exercise | Ask about their staff composition and how they handle complex structures |
Audit defense | A poorly defensible study can backfire in IRS review | Ask: “What if the IRS challenges your study?” and see what they offer |
Transparent methodology | You want to see how they assign costs & classify assets | Ask for sample reports or templates |
Track record | Past performance is the best predictor of future quality | Request case studies or references |
